The autonomic nervous system is controlled by nerve centers in the spinal cord and brain stem. It is also influenced by the midbrain and cortex, and the cognitive centers affect reactions such as blushing.Regarding the actual brain structure that contains autonomic centers regulating heart rate, respiration and other visceral activities, the answer is the medulla.*The medulla also is mainly composed of fiber tracts.
